Embodiment 1

[0029] Such as figure 1 The flow chart of the method for measuring human pulse provided by Embodiment 1 of the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0030] In step S101, multiple frames of light-transmitting finger bitmaps are collected continuously at preset time intervals.

[0031] In the embodiment of the present invention, the finger bitmap is collected by a camera or a video input device. After obtaining one frame of light-transmitting finger bitmap, the second frame of finger bitmap is collected again after a preset time interval, and cycle according to this rule to collect multiple frames of light-transmitting finger bitmap.

[0032] Wherein, the number of finger bitmaps to be collected may be preset, or the collection may be stopped when a signal to stop collecting finger bitmaps is received or the finger leaves the collection area.

[0033] In step S102, the ...

Embodiment 2

[0045] see image 3 , image 3 The second embodiment of the present invention provides a flow chart of the method for obtaining the red value saturation (the above step S102) of the pulse measurement area pixels in the finger bitmap in each frame of the method for measuring the human pulse. Invention Embodiment One Differential Part.

[0046] In Embodiment 2 of the present invention, the method for performing the above-mentioned acquisition of the red value saturation of the pulse measurement area pixel in each frame of the finger bitmap (the above-mentioned step S102) mainly includes:

[0047] In step S301 , a set of pixel points in an elliptical area where finger pressure is uniformly distributed in each frame of the finger bitmap is intercepted.

[0048] In the embodiment of the present invention, after collecting the finger bitmap, according to the pixels of the camera and other factors that may affect the finger bitmap, a rectangular area in the finger bitmap is interce...

Embodiment 3

[0054] Such as Figure 5 Shown is the method flow for obtaining the peak values ​​of the area of ​​the shape within multiple preset time periods in the method for measuring human pulse in Embodiment 3 of the present invention, and calculating the human pulse frequency (above step S105) according to the time difference of multiple peak values In the figure, for convenience of explanation, only the parts different from the first embodiment of the present invention are shown.

[0055] In Embodiment 3 of the present invention, the step of obtaining the peak values ​​of the areas of the shapes within a plurality of preset time periods, and calculating the pulse rate of the human body according to the time difference of the peak areas of the shapes (above step S105) mainly includes:

[0056] In step S501, the peak area of ​​the shape within a preset time period is acquired, and the peak area of ​​the shape is used as a baseline.

[0057] In the embodiment of the present invention, ...

Abstract

The invention is applicable to the technical field of computers and provides a method and a device for measuring the human body pulse. The method comprises the following steps that: multiple frames of light transmission finger bitmaps are continuously collected according to the preset time intervals; the red value saturation of the pixel points in the pulse measurement region in each frame of finger bitmap is obtained; a red value saturation rectangular coordinate system adopting the horizontal axis for representing pixel point sequence numbers and adopting the vertical axis for representing pixel points is respectively built for each finger bitmap, in addition, dotting is carried out in the rectangular coordinate system according to the red value saturation in the finger bitmaps, and thedotted points are connected for forming a red value saturation curve; the area of shapes circulated by the horizontal axis and the vertical axis in each coordinate and the red value saturation curve is respectively calculated; a plurality of shape area peak values are obtained, and in addition, the human body pulse frequency is calculated according to the time difference of the shape area peak values. The human body pulse frequency can be calculated only through electronic equipment, such as computers with cameras, mobile phones and the like, users can conveniently measure the pulse, and the development cost of special pulse test devices is reduced.

Description

technical field [0001] The invention belongs to the technical field of computers, in particular to a method and device for measuring human pulse. Background technique [0002] In modern society, people pay more and more attention to health, and pulse rate, which is an important indicator of human health, has become indispensable for daily health detection. [0003] In the existing pulse measurement methods, dedicated heart rate measurement devices are usually used, such as blood pressure monitors, etc., but most of the existing pulse measurement devices rely on specific hardware, which is not only inconvenient to carry, but also has high development costs. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a method for measuring human pulse, aiming at solving the problems that existing hardware pulse measuring instruments are not portable and have high development costs. [0005] The embodiment of the present invention...
